Answer:
x = 100
Step-by-step explanation:
The area of the left square is 3600
A =s^2
3600 = s^2
Taking the square root of each side
60 =s
The area of the right square is 1600
A =s^2
1600 = s^2
Taking the square root of each side
40 =s
Adding the lengths
60+40 =x
100 =x
Answer:
this should be 450° hahah sorry if I am wrong I don't know!
Mathematical Work:
f(x)=x+8
g(x)=x2-6x-7
f(g(2))=(2^2-6(2)-7)+8
f(g(2))=(4-12-7)+8
f(g(2))=-7
Explanation:
f(x)=x+8
g(x)=x2-6x-7
f(g(2))=?
2 was given as the x for function g and when you substitute 2 into function g's equation(g(2)=(2^2-6(2)-7)=-15, you would get -15. The answer to function g would be the x for function f. Which would be f(-15)=-15+8 and the answer for f(g(2)) is -7.
His error is he forgot the 2 in 2 3/4
